中文摘要：
提出了一种覆盖GPS、格洛纳斯和北斗3种全球卫星导航系统频点的一种天线,利用阿基米德平面螺旋天线的宽带特性实现了1.2-2.6GHz的频带全覆盖。天线通过改进巴伦降低了剖面,使用金属背腔获得了定向辐射,并在背腔上开槽优化了驻波和轴比。按照设计尺寸对天线进行加工,测试结果表明天线性能较好,在全频段内增益大于3dBi,驻波小于1.8,轴比小于4dB。
英文摘要：
An Archimedean spiral antenna was designed for global navigation satellite system （GNSS）, which included GPS, GLONASS and BD. The proposed antenna had the wide band covered from 1.2 GHz to 2.6 GHz. The balun was improved to lower the profile. Moreover, the PEC-backed cavity was used to obtain a unidirectional beam. The ring slot was designed to improve the VSWR and the axial ratio. The antenna was fabricated and the measured results showed that the antenna had a gain greater than 3 dBi;the VSWR and the axial ratio were separately less than 1.8 and 4 dB.
